GUN-CARRIAGE FOR REGOILING GUNS.

Neuilly-sur-Seme,

Gun-Carriages for Recoiling Guns, which is fully set forth in thefollowing specification.

This invention has reference to a longrecoil gun carriage or mountingfor firing at high angle: of elevation and will be described inconnection with the accompanying drawin s, in which,

Y igure -1 is a diagram of the usual a pliances. Figs. 2 and 3 show insectiona elevation, and in partial plan res ectively, an example of theapplication of the invention. Fig. 4 is a diagram of a second example ofits application.

A gun mounted upon a slideway which permite it to recoil for a longdistance (more than a meter) could not readily operate at large anglesof elevation (60) if the trunnions were laced in proximity to the centerof gravity.

nfact, with such angles it would be necessary,

as shown in Fig. 1, in order that the breech a should not encounter theground when it reaches a at the end of the recoil, to considerably raisethe trunnions c of the gun, which would result in giving the carriage ean inadmissible height. i

In accordance with the present invention, the gun-trunnions c arearranged upon the carriage e considerably -beyond the center of avity oithe system comprised by the gun and the slideway cl. Assuming that thissystem bd rotates around the axis 0, it is obvious that whatever theangle of elevation may be, the breech a. is able to make a long recoilbetween the cheeks of the carriage, without encountering the ground, andthis without the necessity of raising the trunnions c, and consequentlyof increasing the height of the gun carriage be 0nd that of existingcarriages. Neverthe ess, as the weight of the gun-slideway system b--dis considerable, and owing to the fact that the center of gravity issituated largely in front oi the trunnions c, it would be difiicult toraise the system in elevating the gun, and the invention therefore alsocom rises means for facilitatin this operation. hese means consist broady, in an antagonistic or.bal ancmg device formed by a system oi metalSpecification of Letters Patent.

springs, or pneumatic or hydropneumatic contrivances, which, are sosupported on the gun carriage that they constantly exert ,upon thesystem constituted by the slideway and the gun, a tractive eiiorttending to raise this system, the said eiiort being applied at a pointon the slideway-opposite to the center of gravity of the said system,the trunnions of the gun.

In the form of the invention illustrated by Figs. 2 and 3, the slideway(I may for this purpose be extended in the form of two arms descendingbelow the axis 0 into the space etween the side cheeks of the guncarriage. In a cylinder g carried by the carriage there is arrangedbetween the trunnions c and the wheel-axle h, a spring a, constantlytending to draw the arms f One extremity of this spring bears against vthe bottom of the cylinder,

towards the wheel-axle.

and its other extremity acts upon a piston the rod of which is coupledto a cross-piece guided by-rollers m in grooves n of the cheeks of thegun carriage. There are likewise coupled to this crossiece, rods 0 towhich chains'p are attache Each of these chains is also fixed to a pointon a cam q keyed to a cross-piece 1- carried by the arms f; the saidchains being wound upon the surface of the cams. .The gun slidewaysystem on the one hand, and the antagonistic system on the other hand,may be arranged in e ance, about the axis 0 the trunnions c.

The metal spring of the balancing device might. be replaced either 'by apneumatic sprin or by a pump body containin liquid a rea y underpressure, or place under pressure by means of .a pump. In either casethe anta onistic tension should be regulated in sue a manner that itsmoment relatively to the axis of the trunnions c is at all times equalto the value of the moment of the wei ht of the gun and of the slidewayrelative y to the said .axis. The balanced on-slideway system being capale of ready ciange in elevation, any known e evating mechanism foreffecting the changes may be employed, for example, a large toothedsector spivoted to one of the trunnions c as center, and meshing with apinion t carried by a spindle u on the gun carriage and with a pinion'0, carried by a spindle a: on

an arm y of the slidewa d. The balanced system above described isintended to apply, to a case in which the axis of displacementrelatively to uilibrium, like. a balof cylinder gis connected over a pulabout the gun trunnions is situated behind the center of gravity (thefront being the muzzle of the gun). The said system 1s obviouslyapplicable in a similar manner to cases in Wl1lCl'l it is necessary todisplace the s stem about an axis otherwise arranged. ig. 4 shows bywayof example the system adapted to be displaced about a point at themuzzle of a gun mounted in a turret in which the embrasure 2 should bereduced to the minimum. In this example, the gun carriage e is assumedto be suspended from the roof of a turret or of a casemate. The saidcarriage is suspended from the roof by a pivot 1 and a segment 2 and iscapable of movement about .thevertical axis of the pivot. The slide-waysystem bdissup orted on the carriage e by trunnions c and the elevationof the system is effected by elevating mechanism in a manner similar tothat already described in connection with that shown in relation to Fig.2. Inthis arrangement, however, the counterbalancin piston Icy g to cam(1 in order that the slide system may be properly counterbalanced.

The axis of elevation formed by the trun nions c and constituting part.of the slideway (Z is perpendicular to the axis of the pivot 1 andlntersects it. It isat the meeting point of these two axes that themuzzle of the gun is situated, that is to say, the front extremity ofthe axis of the gun". The embrasure is therefore reduced to the minimumaround th afipivot thus defined.

hat I claim and desire to secure by Let the weight of the slidewaysystem inits diffierent angular ositions.

,2. In com ination, a gun carriage, a slideway mountedthereon and havinga gun sliding therein, said slideway bein mounted to rock about anaxis.beyond t e center of gravity of said slideway system, apistoncarrying cylinder mounted on said carriage,

a cam on said slideway having a flexible con-- neetion with said piston,said piston acting through said connection on said cam to counterbalancethe weight of. theslideway system in its different angular positions.
